It doesn't.

This shouldn't block adoption, since a dual stack would still be able to access v4, and even a v6-only stack would be able to access v4 via NAT64.

Small/medium sites don't need to be bullied into adoption just yet.

Im not bullying anyone :) My Mac prefers IPV6 it seems, and if i press login on HN I get blank page. It is just annoying. If I set IPV6 in Network Prefs to Link local only, login works.

You probably need to investigate further. It's unclear why disabling IPv6 would have any effect on an IPv4-only website.
